To all whom it may concern: v

Be it known that we, WILLIAM H.' HAN- sEN, andALBnRT J. PRICE, ofChicago, Illinois, have invented certain: new and useful Improvements inBaling-Machines, ofwhich the following is a. specification.

Our invention relates to machines for baling original small packages offlour, salt or the like of uniform size to form bales or large packages.This is ordinarily ,done' by packing a lot of such small packages'in asack or canvas covering byhand. I The chief object of ourinvention is toprovide a machine for. doing such work; We have attained this object bythe machine constructed as illustrated in the accompanying drawing inwhich 1 Figure 1 is a vertical'longitudinal section of a machineembodying our invention. .Fig. l is a detail showing a section at line 11 of Fig. 1. Fig. 2 is a top or plan view of the machine. 7 1% Y YSimilar signs marked on the several views refer to like parts. I i Asuitable frame is provided consisting of uprights, 3, side pieces 4:,and bottompieces 5 connected together and properlybraced againstracking. At the front end/and, for a suitable length along the frame thespace between the side pieces is provided 'with top pieces 6 arranged toform a platform provided with longitudinal slots 7. On this slottedplatform is mounted a flaring slightly tapering hood-like structure 8which terminates in a slightly flattened filling tube 9. The hoodmounting consists preferably of a strong band-like piece 10 secured tothe hood at its junction with the filling tube and V bolted to theframe, and flanges 11 of the hood bolted to the slotted platform, sothat the hood will carry the filling tube and hold it extended free ofthe platform and frame.

The hood is designed and adapted to compress together a lot of smallpackages of uniform size sufficient to fill its cross section by havingthe same forced through it from the large to the small end and todeliver the same into the filling tube so as to fit and fill its crosssection. The bale covering, a canvas sack, is drawn over the fillingtube so that when said small packages are forced through said tube theywill be delivered into the covering and will fill its cross sectlon andpush it ofi of said tube.

The larger or flaring end of the hood is open and unobstructed by acover or any rigid part of the machine so that a pack of original smallpackages placed on the platform or presented at the large end can bepushed into the hood. The taper of the hood interior is uniform andadapted to compress are pushed through it'to'make them closely I fit thebore of the tube. There should be no abrupt or sudden contraction of thepassage way anywhere throughout the hood and tube such as would tend todisarrange the packs, or retard their passage any more than is producedby the uniform taper of the hood to compress them in the mannerdescribed to make them closely fit in the tube. The hood and tube arearranged horizontally in the machine.

Journaled in the side pieces of the frame areshafts 12 carrying sprocketwheels 13 ,over which sprocket chain belts 13 are appliedso as to workinthe platform slots 7.

'ltwhichfjtravel back and forth along the platform and through the hoodso that a pack ofsmall packages placed orderly together upon theplatformbetween the flaring open end of the hood and the ingoing arms'willhecaught by the latter and forced through into the filling tube'9.

1 The driving mechanism consists of a shaft 15 which, at one end,isprovided with a fired pulley 16v and .two loose pulleys 17. These areprovidedjwith a straight belt 18 and aftwisted belt 19 extending to apower pulley 20; Theother end of shaft 15 is geared with the cogged gear21 of the rear- ,most 'of the shafts 12.. q I

A sliding 'bar 22' is mounted on the frame and provided with arms 23adapted to engage the belts 18 and 19 and to shift said belts:alternately from the fast to the loose pulley as said sliding bar isshifted in opposite directions. By this means the motion is reversed soas to cause the arms 14 to oscillate in the slots 7 throughout thelength of the slotted platform. Means for automatically causing this"shifting movement comprises a sliding bar 24c'mounted on the frameimmediately below one of the sprocket chains 13 and provided with lugs25 which: are adapted to engage a lug 26 on said chain. A bell-lever 27(dotted lines Fig. 2)-mounted on the frame has one of its arms connectedwith the slidingbar22 and the other'with said sliding bar 24, thearrangement being such that the lug 2 6 traveling in one directhe packslaterally and gradually as they The chains carry upwardly-projectingarms tion and striking one of the lugs will cause the belts l8 and 19 tobe shifted and reverse the movement, and when traveling in the otherdirection will produce a. substantially similar effect in the otherdirection, thus automatically producing a constant oscillating movementof the arms 14: along the slotted platform and back and forth throughthe hood.

IVe have further provided means for setting the belts 18 and 19 on theloose pulley 17 so that the machine may remain at rest without shuttingoff the power. This consists of a lever 28 mounted on the frame andconnected at one end with the sliding bar 22, the other end beingprovided with a latch or locking means at 29 (Fig. 1 whereby it may beheld so as to keep the arms 23 in the required position to keep thebelts 18 and 19 in the neutral position.

At the rear the frame is provided with a track 30 upon which a truck 31is placed and adapted to travel back and forth under the filling tube 9.r The track is divided into two car lengths, the rear length beingsupported on a rock shaft 32 upon which it may tilt. The rear length isprovided with a springlatch'33 which is adapted to engage automaticallywith a suitable catch 3st, or beveled striking plate, on the frame whensaid rear length of the track is turned up to a level position. The saidrear length is provided with buffers 35 at the extreme rear end whichare adapted to prevent the rear wheels of the truck from passing clearoff of the track.

The front of the truck is provided with an arm 36 which is adapted tostrike the upright part of latch 33, when the truck is movedsufficiently back on the track and unlatch said rear length. IVhen thisoccurs the rear wheels of the truck strike the buffers 35, the truck isunbalanced on the rock-shaft so that the said rear length and truck willtogether tilt from a horizontal to a vertical position. In this positionthe truck is held at the lower end to said rear length by the wheelsresting on the buffers 35 which are curved back to prevent the wheelsfrom rolling off, and at the upper end by a keeper 37 which the arm 36passes under before striking the latch 33, so as to engage said keeperand prevent the upper end of the truck from falling away from the track.

The rear end of the truck is provided with stakes 38 designed to preventthe load from slipping off when the truck is so tilted.

The size of the hood and filling tube in cross section is adapted to thesize of the small packages so that a given number of the packages laidtwo or three in a line and piled correspondingly upon one another acrossthe platform will substantially fill the cross section of the hood atthe large end, and being forced through to the small end and into thefilling tube will be compressed transversely of the hood so as to takeup all the looseness and cause a close fit of the pack in said tube.Preferably the length of the filling tube corresponds with the length ofthe bale which also, preferably corresponds in length with a definitenumber of the small packages laid lengthwise in the tube. The weight andfriction of the packages in the hood and tube yield all desired endwisecompression.

The bale covering is drawn over the filling tube and has its bottomresting against the stakes 38 of the truck shoved under the tube. Thelength of the truck also preferably corresponds with the length of thebale.

The feeding of the machine consists in the regular and orderly piling ofthe small packages across the slotted platform as be fore described infront of the arms letwhen they are moving toward the hood. T he volumerequired to fill the bale is forced through the filling tube by repeatedimpulses of said oscillating arms the number varying as the feedingvaries. As the bale is pushed off of the tube it rests upon the truckand is thereby carried back until the truck is tilted. This operationsquarely separates the packages in the bale covering from thoseremaining in the filling tube at the end of said tube. Then the feedingis stopped, another bale sack is drawn over the tube, the truck turnedup to horizontal and pushed back under the filling tube, and the feedingresumed. The oscillating motion of the arms is continuous and does notstop during any of the other operations unless the lever 28 is set inneutral position.

The hood and filling tube are preferably made detachable from the framein order to substitute different sizes when changes in the sizes ofsmall original packages are made, as when a pack of a given number wouldnot fill the cross section of the filling tube.

lVhat we claim is:

1.
